There was an easter egg where you could press Ctrl-F12 and type in a "command" into the text entry box. These would unlock some special hidden functionality like changing your icon to one only available via that command (presumably for the devs of the software so they could have an exclusive user icon), or encipher your chat messages with a basic offset-substitution cipher. There were others that would restrict your chat to only saying "oink!" and turning your icon into a pig -- this was used as a prank to use on people "Hey dude if you press Ctrl-F12 and type fuelharp you'll get secret admin access!" (only to have them turn into a pig) :) Another Ctrl-F12 command would report your upload/download ratio into the chat - either a fun way to brag about your good ratio, or a good one to bait perennial leeches into typing so they'd inadvertantly reveal their pesky leeching ways!
Anyway, all in all a really fun place for a few years where it was "the" online destination for Mac users. I spent an ungodly amount of hours on there (and still hop on pretty often). :)
Often there was a requests directory in the top level with you would need to upload a requested album/program in order to get access to the entire server. There was also banner clicking to get a password, but that never worked tbh.
